軟起動(dòng)器就是應(yīng)用**效用**突出的控制設(shè)備,軟啟動(dòng)器在不同領(lǐng)域、不同行業(yè)甚至是不同設(shè)備上的應(yīng)用往往也有著極大的不同。1、軟起動(dòng)器在城市雨水排污泵站、污水處理廠中的應(yīng)用雨水排污站的泄水池是雨水、生活污水、工業(yè)污水的集中地，為確保泄水池液位保持在允許的范圍內(nèi)，通過(guò)檢測(cè)泄水池液位來(lái)自動(dòng)控制排污泵組工作以保證污水的正常排放。2、軟起動(dòng)器應(yīng)用于自來(lái)水廠、加壓泵站清水泵主要實(shí)現(xiàn)大功率水泵電機(jī)的軟起動(dòng)、軟停車，重點(diǎn)消除、減弱水錘的危害。當(dāng)液體在管路系統(tǒng)中受外力突然加速或突然減速、或改變流向就會(huì)造成水錘，水錘危害很大，輕則引起管路，系統(tǒng)振動(dòng)，發(fā)出噪聲，重則造成損壞，甚至使泵房被淹。3、軟起動(dòng)器在消防泵控制中的應(yīng)用消火栓泵、噴淋泵是工業(yè)和民用建筑消防設(shè)施的重要消防裝備，其運(yùn)行可靠性極其重要，隨著大中型建設(shè)項(xiàng)目的興建，所配置的消火栓泵、噴淋泵功率、揚(yáng)程增大，傳統(tǒng)的降壓起動(dòng)方式凸顯其缺點(diǎn)，尤其高層建筑水錘危害嚴(yán)重，給設(shè)備運(yùn)行帶來(lái)不安全因素，目前軟起動(dòng)在消防泵控制中得到的應(yīng)用。4、軟起動(dòng)器在在各種類型的深井潛水泵、長(zhǎng)軸泵中的應(yīng)用一般深井潛水泵揚(yáng)程較大，非軟停機(jī)時(shí)水錘現(xiàn)象明顯。淄博科恩軟啟動(dòng)器銷售電話</p><div

變頻器和軟啟動(dòng)器是兩種完全不同用途的產(chǎn)品。變頻器主要是用于需要電動(dòng)機(jī)調(diào)速的地方，因此也被稱為變頻調(diào)速器，其輸出不但改變電壓而且同時(shí)改變頻率。變頻器具備所有軟啟動(dòng)器和其他啟動(dòng)控制裝置的功能，且啟動(dòng)特性上較之其他電動(dòng)機(jī)啟動(dòng)裝置有比較大的優(yōu)勢(shì).因此完全可以用作電動(dòng)機(jī)的軟啟動(dòng)控制。但之所以目前在電動(dòng)機(jī)的啟動(dòng)控制領(lǐng)城軟啟動(dòng)器仍占據(jù)主要位置.是由于變頻器固有的一些劣勢(shì)，且短期內(nèi)很難克服.只有克服了這些劣勢(shì)之后.變頻器才有可能取代軟啟動(dòng)器。變頻器的特點(diǎn)：(1)啟動(dòng)轉(zhuǎn)矩大，功率因數(shù)高。因?yàn)殡妱?dòng)機(jī)的功率因數(shù)與工作頻率有關(guān)，在電動(dòng)機(jī)低速運(yùn)行時(shí)工頻電源下的功率因數(shù)遠(yuǎn)低于低頻電源下的功率因數(shù)。變頻器可以控制電動(dòng)機(jī)從低頻起步.且在整個(gè)啟動(dòng)過(guò)程中在接近額定電流的條件下始終保持比較高的功率因數(shù)和接近額定轉(zhuǎn)矩的輸出轉(zhuǎn)矩。(2)輕載或空載條件下.或啟動(dòng)期間采取減載卸載等措施時(shí).變頻器容量可以比電動(dòng)機(jī)容量小。當(dāng)然，啟動(dòng)完成后變頻器需要退出運(yùn)行。(3)啟動(dòng)電流小。變頻器一電動(dòng)機(jī)拖動(dòng)系統(tǒng)允許的啟動(dòng)時(shí)間可以很長(zhǎng)。因?yàn)樵谶@期間，電動(dòng)機(jī)電流可以不超過(guò)電動(dòng)機(jī)額定電流，因此，不論是變頻器、電動(dòng)機(jī)還是其他元器件均沒(méi)有超常地發(fā)熱。

電動(dòng)機(jī)的啟動(dòng)指標(biāo)啟動(dòng)（startion）是指電動(dòng)機(jī)從靜止?fàn)顟B(tài)開(kāi)始轉(zhuǎn)動(dòng)起來(lái)．直至達(dá)到穩(wěn)定運(yùn)行。對(duì)干任何一臺(tái)電動(dòng)機(jī)．在啟動(dòng)時(shí)．都有下列兩個(gè)基本的要求。啟動(dòng)轉(zhuǎn)矩要足夠大．只有Tｎ>TL時(shí)．電動(dòng)機(jī)才能改變?cè)瓉?lái)的靜止?fàn)顟B(tài)．拖動(dòng)生產(chǎn)機(jī)械運(yùn)轉(zhuǎn)。一般要求Tn≥()TL,Tn越大于TL．啟動(dòng)過(guò)程所需要的時(shí)間就越短。啟動(dòng)電流不要超過(guò)允許范圍。對(duì)三相異步電動(dòng)機(jī)來(lái)說(shuō)．由干啟動(dòng)瞬間s=1,旋轉(zhuǎn)磁場(chǎng)與轉(zhuǎn)子之間的相對(duì)運(yùn)動(dòng)速度很大．轉(zhuǎn)子電路的感應(yīng)電動(dòng)勢(shì)及電流都很大．所以．啟動(dòng)電流遠(yuǎn)大干額定電流．在電源容量與電動(dòng)機(jī)的額定功率相比不是足夠大時(shí)．會(huì)引起輸電線路上電壓降的增加．造成供電電壓的明顯下降．不僅影響了同一供電系統(tǒng)中其他負(fù)載的工作，而且會(huì)延長(zhǎng)電動(dòng)機(jī)本身的啟動(dòng)時(shí)間。此外在啟動(dòng)過(guò)干頻繁時(shí)，還會(huì)引起電動(dòng)機(jī)過(guò)熱。在這兩種情況下．就必須設(shè)法減小啟動(dòng)電流．下面分別介紹籠型和繞線型異步電動(dòng)饑的啟動(dòng)方法．異步電動(dòng)機(jī)啟動(dòng)籠型異步電動(dòng)機(jī)的直接啟動(dòng)直接啟動(dòng)又稱為全壓?jiǎn)?dòng)．就是將電動(dòng)機(jī)的定子繞組直接加上額定電壓?jiǎn)?dòng)．直接啟動(dòng)電流雖然很大．但因啟動(dòng)時(shí)間很短．而且隨著轉(zhuǎn)子轉(zhuǎn)動(dòng)起來(lái)后。電流很快減?。灰獑?dòng)不過(guò)于頻繁．不致引起電動(dòng)機(jī)過(guò)熱。

現(xiàn)在跟大家講講根據(jù)負(fù)載性質(zhì)選擇不同型號(hào)的軟啟動(dòng)器來(lái)選用軟啟動(dòng)器軟啟動(dòng)器選型：目前市場(chǎng)上常見(jiàn)的軟啟動(dòng)器有旁路型軟啟動(dòng)器、無(wú)旁路型軟啟動(dòng)器、節(jié)能型軟啟動(dòng)器等。下面我們來(lái)一一講它們的功能：旁路型軟啟動(dòng)器：在電動(dòng)機(jī)達(dá)到額定轉(zhuǎn)數(shù)時(shí)，用旁路接觸器取代已完成任務(wù)的軟啟動(dòng)器，降低晶閘管的熱損耗，提高其工作效率。也可以用一臺(tái)軟啟動(dòng)器去啟動(dòng)多臺(tái)電動(dòng)機(jī)。無(wú)旁路型軟啟動(dòng)器：晶閘管處于全導(dǎo)通狀態(tài)，電動(dòng)機(jī)工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時(shí)重復(fù)工作的電動(dòng)機(jī)。節(jié)能型軟啟動(dòng)器：當(dāng)電動(dòng)機(jī)負(fù)荷較輕時(shí)，軟啟動(dòng)器自動(dòng)降低施加于電動(dòng)機(jī)定子上的電壓，減少電動(dòng)機(jī)電流勵(lì)磁分量，提高電動(dòng)機(jī)功率因數(shù)。軟啟動(dòng)器如何選規(guī)格?根據(jù)電動(dòng)機(jī)的標(biāo)稱功率，電流負(fù)載性質(zhì)選擇啟動(dòng)器，一般軟啟動(dòng)器容量稍大于電動(dòng)機(jī)工作電流，還應(yīng)考慮保護(hù)作用是否完備，例如：缺相保護(hù)、短路保護(hù)、過(guò)載保護(hù)、逆序保護(hù)、過(guò)壓保護(hù)、欠壓保護(hù)等。淄博科恩軟啟動(dòng)器銷售電話</p><p
